Thanks Sleeper but I recall seeing a Aggressor chart with Aggressor's name on it. I know the Berk chart is close, just wanted to have a look see at the other.

I plowed through every impeller chart thread on the site, and i didn't see an aggressor one, closest i found was a dominator one, and the HTP one. And i didn't see one on the aggressor site either. But im not trying to say that it doesn't exist either. But if im not mistaken, don't you just have to drop down 1 impeller size and you can use the berkeley chart and get pretty close.

Sometime ago I published a chart on Impellers. I lost it or it got burned up in our fire. There was a gentleman had spent some time on trying to graph our Impeller from No Cal. If I am not mistaken he did the Berkeley chart. He gave me some factor ratios for charting but said the data provided a variable to the factor. It seems the Impeller had a efficiency factor Improvment as more power was applied. I don't know if he still gets involved in the boards or not. Maybe if he see's this he will respond.
Untill then you need to use the Berkeley Chart, just drop 1 cut to our impeller to get close. An Example: 375 HP is 4200 on our "A" I think a Berkeley "A"
is 4600. So our "B" is there "A" Our "B" will out launch there "A". Hope this helps. Dave

Thanks Pops, I've been running your full uncut(A) for years now, max RPM (good cool air day 52/5300). But would it really cross over to a Berk 2-A as some suggest?
